BEIJING, June 18  -- China will work with its partners to develop the Belt and Road into a model of cooperation for meeting challenges through unity, President Xi Jinping said Thursday in a written message to the High-level Video Conference on Belt and Road International Cooperation.

The Belt and Road will also be a model of health for protecting people's safety and well-being, a model of recovery for restoring economic and social activity, and a model of growth for unlocking development potential, Xi said.

The video conference is "a highly important meeting that gives Belt and Road cooperation partners an opportunity to discuss a collective response to COVID-19, advance Belt and Road cooperation, and strengthen international solidarity and cooperation," said Xi.

He said that the sudden attack of COVID-19 has posed a grave threat to the lives and health of people across the globe. It has dealt a heavy blow to the world economy, and caused tough economic and social challenges for some countries, developing ones in particular.

"To contain the virus, countries have taken robust and effective measures, specific to their national context. On top of that, many countries are striving to resume economic and social development," Xi said, noting that in China's case, the people's lives and well-being have always been put front and center.
